eating food while hiding under it

Browse Source 
Fix the bug reported by entrez where you could end up hiding under
nothing if while poly'd into a hides-under creature and hiding under
something edible you ate whatever you were hiding under.  Same thing
could happen if it was a corpse on an altar and you offered it rather
than consumed it.

While in there, fix monsters hiding under cockatrice corpses.  They
won't do that unless there are multiple objects in the pile, but
there was no check for the possible case of all additional objects
also being other cockatrice corpses.
